/ I think no one is doing anything. Richard is trying to stun her with a jump (if he can't disarm her when she's frozen. If he can, he disarms her).
Then everyone focuses on the archer. Except for one person who tries to pick up the weapon from the ground if it was actually disarmed.
That's one option. The second is to try to figure out how the archer is losing health from the freezing. Maybe she doesn't have immunity to magic? Maybe we can just keep her frozen for 20 rounds and guarantee that we finish her off? If she loses 5% health per round./

Just don't drag out the fight, please. It would be good to finish it today.
